Has anyone ever attempted to find sound recordings out in the world that weren't made with human technology?

Pre-digital, pre-tape sound recordings are based on engraving vibrations in different ways. This makes me wonder: has any research attempted to find ways to play back naturally engraved sound vibrations, perhaps on a microscopic scale?
For example, what if a loud sound caused a hard substance to etch a durable surface in a way that could be listened to later? I'm curious whether this possibility is being--or has ever been--explored by scientists.
This was a late night, stare-at-the-ceiling thought I had. So feel free, if necessary, to tell me why this would be impossible, utterly improbable, or just silly.
